Poultry observations, ('. K. (Jkaiiam (('oniiccliciif Sfarrs Sfd. Bui. J///, pp. 

 2')--l'i. fi'/s. .1). 'I'lic nutlKir stiidii'd tiie e.iuscs of iiiuii mortality so often noted 

 with yoiiii;,' chic-ks and the effects of sulislitutin.i,' snow for driiikiiii:: water with 

 layiii.:,' hens and chickens. 



When newly hatched chicks were uiven food mixtures containing salt, saw- 

 dust, supir. and musty j^rains in .-iddition to the usual feeds, it was noted that 

 llio salt and sufj:ar were selected first, perhaps owinj? to their hright appearance, 

 and that musty grain or sawdust was as readily eaten as more suitable food, 

 ("hicks S ()!• '.» days old showed more discrimination in the selection of the 

 inateri.-ils eaten, and therefore the author believes that the death of very young 

 chicks is often caused by eating musty grain accidentally present in their other 

 feed, altliough as shown by the observations re|)oi-ted "there is no doubt th.-it 

 l.iully liidoders, cliills. overheating, improper ventilation, and lack of vitality 

 ill the p.'ireiit stock should all receive jiroper credit for their share." 



When snow was supplied instead of water to laying hens it was noted that 

 old hens were more affected than young Itirds. In one of the tests the egg 

 production of the old hens was smaller "on the days when snow was on the 

 ground, and also considerably less when the ground was frozen; that is, on the 

 (old (lays when water was not accessible. These conditions do not seem to have 

 .•iffected the younger birds. ;iiid they show an increase in eggs immediately after 

 each snow storm, gradually drojiping bade ;is tlie snow disajipears." 



In .•mother test made under similar ((Miditions, except that the houses were 

 located in a drier locality "the cold weather did not affect the egg production, 

 lut there was a noticeable increase in the amount of grain eaten during the 

 cold weeks, when com])arison is made with the very mild ones. This, however, 

 may have been caused by the birds foniging more during the milder periods. 

 These bii-ds did not appear to mind tli<> cold and there was not the slightest 

 sign of frosted combs among them, nor were there any colds." 



Data regarding other lots ar(> brieliy i^ejiorted and in gener.il it was noted 

 that " wlien snow was given there was gener.nlly an extra .•unount of feed 

 re(|uired. .-iltliougii the increase in eggs moi-e than jiaid for it." " Th(» time 

 saved by using snow and dry m.ashes amounted to nearly half that re(iuired in 

 tending the fowls." 



When cold wat(M- was comiiarod with warm water the average egg yield w;is 

 much the s;ime. tliougli slightly in favor of tbe latter. 



"Snow was given to young cliicks. but the I'esults were disastrous; although 

 chicks that were reared in (Jiitdoor brooders were let run on the snow crust 

 during bright days when .'{ weeks old or o\-er .-ind no serious results followed."

 with poultry feeding and in this bulletin an account is given of the equijiment 

 and jilans. 



To meet tbe present demands foi- information on various jioints connected 

 with poultry raising, a general summary of d.ata on tbe subject has been pre- 

 pared, including such topics as food and exercise, selection and mating, incu- 

 liatioii, broo(lJng. bandling young stock, feeding, care and niiinagement of pullets 

 during fall and winter, construction of poultry buildings, and some diseases of 

 chicks.
